How to troubleshoot Huawei Honor V10 that can’t detect SD cards?

Before you troubleshoot software errors that may have prevented the phone from reading the card, verify and ensure that your microSD card is functional or not damaged. If possible, use a new and formatted SD card that’s supported by your Honor V10 smartphone. Proceed to troubleshooting if your SD card is new and formatted but still not read or detected by your phone.

First solution: Soft reset/reboot your phone.

It’s possible that your phone is just experiencing some random glitches and therefore failed to read the external storage media at first. If that is so, then performing a soft reset or restarting the phone will most likely fix the problem. A soft reset is a simple yet very effective solution to various types of software errors in mobile devices. And it works without affecting any saved data on the internal memory of the phone so you won’t lose any critical information. Here’s how a soft reset is done on your Honor V10 smartphone:

  1. Press the Power button for a few seconds and then release when the menu option pops up.
  2. Select Power off option then tap OK to confirm. Your phone will then shut down.
  3. After 30 seconds, press the Power button to turn on your phone again.

After restarting, insert then mount your SD card again and see if it’s already detected by your phone this time.

Second solution: Unmount then remove your SD card.

If a soft reset doesn’t fix the problem, then consider unmounting the SD card to remove it from your phone. Your card might have been dislodged or not properly seated into the SD card slot and therefore it couldn’t be detected. Before removing the card, be sure to unmount or eject it with these steps:

  1. Go to Settings.
  2. Tap Storage.
  3. Then tap the Unmount or Eject icon next to your SD card.

Once ejected, you can safely remove the SD card from your phone. To do so, turn off your phone and then use the ejector tool to pop the SD card tray out. Then gently remove the SD card from the tray. Check and see if there are any signs of damage on the card or SD card slot. If there’s none, then place the SD card back into the slot. Be sure to position the card in the right way, usually with the gold contacts facing downwards. Secure the card in place and then push the tray back into the phone. Once the tray is secured, turn on your phone, mount the card then try to access it.

Third solution: Erase or format your SD card on a computer.

The microSD card you’re using might have been corrupted and needs to be reformatted. Formatting means wiping everything from the card, so any saved data will be erased. If possible, format the microSD card on a computer so that you can specify which format type to use. Here’s how to format an SD card on a Windows computer:

Insert the SD card into your computer’s SD card slot. If necessary, use an SD card reader or adapter.

  1. If you’re using a Windows computer, navigate to Start-> File Explorer-> My Computer-> Devices and drives, and then click on your SD card’s name.
  2. Then click the Manage tab to view more options.
  3. Click Format.
  4. Select exFAT (Recommended) from the dropdown options. This is a recommended format for bigger file storage.
  5. Check the Quick Format box, if necessary.
  6. Then click the Start button to begin SD card formatting.
  7. If prompted with a warning message, click OK to confirm.

To format your microSD card on Mac, refer to these steps:

  1. Insert the card into the SD card slot on your computer or use an SD-to-USB adapter to connect your SD card.
  2. Open the Finder icon in the Dock.
  3. Click on the Go menu.
  4. Scroll down to and select Utilities.
  5. Double-click Disk Utility.
  6. Click on your SD card’s name in the left-side of the Disk Utility page.
  7. Then click the Erase icon.
  8. Select ExFAT (Recommended) format option from the dropdown list. This format works on both Windows and Mac computers and has no storage limit.
  9. If prompted, specify the name for your SD card, if desired and then click Erase twice to confirm.

The computer will then begin erasing and reformatting your SD card. After successfully formatting the SD card, try to insert it back into your phone and see if it’s already detected.

Fourth solution: Reset all settings on your phone.

You may continue to troubleshoot your phone and resort to software resets if the problem continues after reformatting the SD card. There may be some settings on the phone that needs to be reconfigured for it to read external storage devices as intended. In that case, you can try to reset all settings on your Honor V10 with these steps:

  1. Tap to open the Settings app from the Home screen.
  2. Select Advanced settings.
  3. Scroll to and tap Backup & reset.
  4. Select the option to Reset all settings. Doing so will reset all settings without affecting data or saved files on the phone.
  5. Tap Reset all Settings again to confirm.

Reboot your phone when the settings reset is finished. Enable necessary options and features individually and configure your device accordingly.

Fifth solution: Wipe cache partition on the phone.

This can help clear system errors due to corrupted system cache. If your phone suddenly failed to read or detect your SD card after installing an update, then wiping cache partition can potentially fix it. Here’s how to wipe cache partition on your Honor V10:

  1. Press and hold the Power button and Volume Up button simultaneously for at least 10 seconds and then release when the Honor logo pops up.
  2. The EMUI screen containing the recovery menu options will then show up on the shortly.

  6. Your phone will then instigate the reset and wipe cache partition. Once it’s done, it’ll prompt you to Reboot system now. Press the Power button to confirm restart.

After wiping cache partition, insert then mount your SD card again. If none of that works and your Honor V10 is still unable to detect or read your microSD card, then consider other options.

Other options

Try to use other new, formatted microSD card and see if any of them works. If your Honor V10 is able to read or detect other SD cards, then the problem is with the previous SD card. Thus, you just need to replace it with the one that’s working.
